SASH-FASTEN ER.

SPECIFICATION forming part of Letters Patent No. 461,020, dated October13, 1891. Application filed April 22, 1891. Serial No. 889,938. (Nomodel.)

To all whom it may concern.-

Be it known that I, WILL S. JAMES, a citizen of the United States,residing at Fort \Vorth, in the county of Tarrant and State of Texas,have invented a new and useful Sash- Lock, of which the following is aspecification.

My invention relates to an improvement in sash-fasteners; and it hasforits object to provide a simple and inexpensive lock that can bereadily adapted to any ordinary sash and window-frame, that willsecurely support the sash at any desired elevation and prevent eitherthe upward or downward movement of the same until the lock is released,and that will be easily controlled and operated; and it consists of aratchet-lock combined with a ratchet-bar and provided with details ofconstruction hereinafter more fully described, illustrated in theaccompanyingdrawings, and specifically pointed out in the appendedclaims.

In the accompanying drawings, Figure 1 is a front elevation of a windowprovided with my improved ratchet-lock. Fig. 2 is a detail in elevationof the lock, showing the bolt secured in its withdrawn position. Fig. 3is a similar view with the bolt-lock in its normal position. Fig. 4 is adetail section of a portion of a sash having the lock placed within thesash-rail. Fig. 5 is a detail in perspective of the flangetoothratchet-bar. Figs. 6 and 7 are similar views of a modification of therack-bar and of the locking-bolt respectively.

Referring to the accompanying drawings by letter, A designates theordinary windowcasing and B the sliding sash. Upon the side rail of thesash is secured a ratchet-lock 0, provided on either side with theperforated lugs c 0, through which the securing-screws 0' pass andattach the lock to the sash. Lock C is constructed of suitable materialand made in any desirable shape, but is preferably tubular, and isprovided with a sliding bolt 0 that is normally pressed out against theratchet-bar D, which is secured to the window-casing adjacent to theside rails of the sash by the spiral spring E within the barrel of thelock. Said ratchet-bar D is made of suitable metal and is provided withflange ratchet-teeth cl, but may be constructed of other material andmay be cast, cut, or corrugated into shape, as shown in the modificationin Fig. 6, in which the corrugations cl form the ratchet-teeth, and thebar may be also made from wood. The outer end of said sliding bolt isbeveled at c to insure its easy movement over the teeth of theratchet-bar, while it is further provided on its end with a groove 0 ofthe same width as that of the ratchet-teeth, being adapted to pass overthe same and steady the bolt and prevent lateral oscillations of thesame, which is usual in spring-actuated bolts of this character, and atthis end is also provided with a squared abutting side 0 that is adaptedto rest flat on the ratchet-teeth when holding the sash. A pin F isscrewedinto the bolt near its beveled end and passes through a slot 0 inthe barrel of the lock, holding the said bolt to its place within thelock and at the same time furnishing means for locking the bolt eitherin its normal or withdrawn position.

On the inner end of the barrel of the lock a lever G is pivoted at g,and is provided at one end with a locking-shoulder g, that is adapted totake behind the pin projecting through the lock-barrel from the bolt andlock the same in its normal position in engagement with the ratchet-bar,while said 1ever is further provided immediately back of saidlocking-shoulder with a notch 1 thatis adapted to pass over said pin andhold the belt out of engagement with the rack when desired, the oppositeend of said lever slightly projecting beyond the point of pivot to forman operating portion g.

hen the lock is placed within the sashrail, as shown in Fig. 4, themodification is slight. The sash is recessed to receive the barrel ofthe lock and is provided with a slot II and a correspondinglyslottedplate I, through which the pin F may work, and upon which is mounted thelocking-lever G. The ratchet-bar in this modification is placed withinthe sash-groove.

According to the direction in which the sash is designed to be lockedthe ratchet-lock can be reversed by simply reversing the ratchet-bar onthe window-casing, unscrewing the pin in the spring-actuated bolt,reversing the same without otherwise disturbing the lock, and thuschanging the direction of the ratchet and of the lock.

The operation of the look can be readily seen from the foregoingdescription. The spring-actuated bolt is adapted to run freely in onedirection over the ratchet-bar and lock the sash at any elevation bycoming into looking engagement with the ratchet-teeth of the rack-barwhen the looking-lever is not used in connection with the same; but bymeans of this lever the bolt can be held locked in its normal positionagainst the ratchet-teeth irrespective of the direction of the teeth andalso is adapted to hold the bolt out of engagement with the same andpermits the free movement of the sash either up or down.

Having described my invention, What I claim, and desire to secure byLetters Patent, 1s

1. In asash-lock, the combination, with a ratchet-bar, of a spring-actuated bolt provided with a projecting pin, and of a locking-leveradapted to engage said pin and hold the bolt locked in its normalposition against the teeth in the ratchet bar and in its withdrawn andinoperative position out of engagement withdrawn and inoperativeposition out of engagement with said teeth, substantially as set forth.1

3. In a sash-lock, the combination, with a ratchet-bar, of aspring-actuated bolt provided with a pin projecting through a slot inthe lock-barrel, a beveled engaging face, a groove in said face that isadapted to pass over the teeth on said ratchet-bar, and a squared sidethat is adapted to form a locking-rest for the bolt, and of alocking-lever pivoted to said barrel and provided at one end with alocking-shoulder that is adapted to abut against the said pin and lockthe bolt in its normal position against the teeth on the ratchet-bar andwith a notch that is designed to pass over said pin and hold the bolt inits Withdrawn and inoperative position, substantially as set forth.

In testimony that I claim the foregoing as my own I have hereto affi Xedmy signature in presence of two witnesses.

WILL S. JAMES.
